Abstract

A 9-point distributed thermocouple was used to measure the temperature field distribution of each layer of the oven in real time, and the oven temperature uniformity was determined and analyzed. Moreover, the internal temperature field of the oven was numerically simulated using computational fluid mechanics knowledge. The results showed that the uniformity of the temperature field inside the oven was significantly improved, by optimizing the structure of the rear baffle in the oven, adjusting the distribution of air volume, and changing the layout of the air outlet.
